The science database issues slowly get better. The root drives are now all sync'ed up, but as I mentioned before this is only a temporary condition. This will fail again upon next bootup. That's fine because this forces the issue of reformatting the data RAIDs on the system which is something I've been wanting to do for a year now - might as well reformat the whole system, root, data, and all. The pulse table continues to get populated and assimilators remain off - at least for another day. We're about to run out of workunit disk storage (again) so expect another workunit shortage period in the very near future. My new rough estimate for the pulse load to finish is sometime tomorrow, and then we can turn the assimilators on, and we will be as back to normal (whatever that means).

One of the download servers (bane) has been having mounting issues the past few days, hence the locking-up of the server status page. I just rebooted the thing. Let's see if that holds.

Once again today was mostly a coding day. I've been annoyed by the radar blanking stuff, being as how the design has changed underneath me thus rendering a week (or two) of my effort moot. The old understanding was that we should only being seeing one type of radar at a time, but my output was showing this to be far from the case. Nevertheless once I got a quick handle on the fftw routines I made quick work of the correlation code and am already spotting radar quicker and more effectively. However a lot of graphing/threshold tweaking is in order before I can really start locking on and blanking.

You know what I mean.. the new program is spotting radar quicker than the old one. Though still you can look at some of a graph of the data and see radar instantaneously.

Considering the mess that the radars are having on the s@h and Astropulse data... What of the other astronomical studies?

Because of the kind of data analysis other projects do, the radar is lost in the noise. It's a nightmare for us because it ends up looking like pulses.

However, some projects are similarly affected and request that when they observe a high pass filter is turned on which completely obliterates the radar (which is actually broadcasting around 1300MHz, but is still loud enough to jam our receivers up at 1420MHz). Unfortunately this high pass filter is only on about 10% of the time, roughly - but when it is our data look super clean.

Is the signal correlation between the channels good enough to do mere common mode rejection to eliminate the radar (and any other common mode signals)?

It is when the radar is blasting us (every 12 seconds) but from what I understand the echoes are weak enough to look like noise (but still show up as pulses). I may be wrong. Ask Eric or Dan.

Some times I feel for you Matt. All the things you have to deal with makes my computer problems seem very trivial. Not knowing exactly where a problem is, has to be the most agravating thing in the world!

I think your doing a great Job and have never seen any loss of control on your part :)

If the WUs go away.. so beit. I will survive and so will everyone else. A full format sounds like an excellent idea. A surface scan is not a bad idea either but would take.. WOW.. who knows!!?? Its ok.. I'll wait :)

I have been getting this for nearly a day now and even though there is work available, none is getting through.

Any suggestions as to why this message is coming up?

Because your task ended with an error. If there's an error, then no scientific work is completed, and there's no output file to upload.

Have a look at the task details for 09fe09aa.16820.11115.6.8.63_1. The error message is "No main program specified". Post that in Q & A or Number Crunching, and we can help you there. (My guess is that Claggy's Space has crept into your app_info.xml file).

The graph froze at 1600 UTC. Another process damming up the processes? Server Status page processes? Science Status page processes?
